Polyaniline-encapsulated quartz sand as an adsorbent composite for Orange G dye removal from aqueous solution: Experimental and computational study

Harnessing a carbon-based material from food waste digestate for dye adsorption: the role of hydrogel beads in enhancing the material stability and regenerative capacity

“…The negative Δ G ° values indicate that MB adsorption onto CM-HNO 3 and CM-HNO 3 @Alginate was spontaneous and more favoured with a temperature increase. 44 Further, the positive Δ H ° values reveal that MB adsorption onto CM-HNO 3 and CM-HNO 3 @Alginate are endothermic processes. 45 Finally, the positive Δ S ° values suggest an increase in randomness at the interface (adsorbent–adsorbate) during the adsorption process.…”

Recent advances in nano-fertilizers: synthesis, crop yield impact, and economic analysis

“…25 Groundwater can be contaminated by chemical fertilizers containing nitrogen, phosphate, and potassium. 26,27 Nitrate-based fertilizers are responsible for methemoglobinemia, which can damage the respiratory and circulatory systems. Studies have shown the impact of chemical fertilizers on water, soil, and air pollution.…”

Alginate@ZnCO2O4for efficient peroxymonosulfate activation towards effective rhodamine B degradation: optimization using response surface methodology

“…The ANOVA was employed to evaluate and authenticate the significance of the quadratic polynomial model for the polynomial quadratic model. 53,54 The ANOVA results for RhB degradation efficiency are displayed in Table S4,† and the statistical significance of the model was determined by the p -value and F -value, where a p -value below 5% signifies that the model is statistically significant. 16,41 The output values of the model presented in Table S3† indicate a strong correlation between the experimental and predicted degradation efficiency (%).…”
